David D. Friedman

He is a long-time science fiction fan, and has written two fantasy novels, Harald (Baen Books, 2006) and Salamander (2011).

In his book The Machinery of Freedom (1973), Friedman sketched a form of anarcho-capitalism where all goods and services including law itself can be produced by the free market. Friedman advocates an incrementalist approach to achieve anarcho-capitalism by gradual privatization of areas that government is involved in, ultimately privatizing the law itself. In the book, he states his opposition to violent anarcho-capitalist revolution.

David Friedman is the son of economists Rose and Milton Friedman. He graduated magna cum laude from Harvard University in 1965, with a bachelor's degree in chemistry and physics. He later earned a master's (1967) and a PhD (1971) in theoretical physics from the University of Chicago. Despite his later career, he never took a class for credit in either economics or law. He was a professor of law at Santa Clara University from 2005 to 2017, and a contributing editor for Liberty magazine. He is currently a Professor Emeritus. He is an atheist. His son, Patri Friedman, has also written about libertarian theory and market anarchism, particularly seasteading.

David Director Friedman (born February 12, 1945) is an American economist, physicist, legal scholar, and anarcho-capitalist theorist. Although he studied chemistry and physics and not law or economics, he is known for his textbook writings on microeconomics and the libertarian theory of anarcho-capitalism, which is the subject of his most popular book, The Machinery of Freedom. Described by Walter Block as a "free-market anarchist" theorist, Friedman has also authored several other books and articles, including Price Theory: An Intermediate Text (1986), Law's Order: What Economics Has to Do with Law and Why It Matters (2000), Hidden Order: The Economics of Everyday Life (1996), and Future Imperfect (2008).
